I just checked, the new free shipping option is from USA warehouse, for orders above $50. I added in cart batteries only. However, from USA Fed-ex might charge duty taxes (usually they call to let you know about extra charges), the brokerage fee is ridiculous. You should call Fed-ex once you have the tracking number. Let them know you will clear yourself with CBSA and ask for the manifest. It is a bit complicated, better use this thread to gather 2-3 for global shipping (min $150). Cheers!
